4'Claims. I c This invention relates to improvements in joggers. V

Heretofore jogging machines have been of heavy construction, cumbersome,complicated in structural details andexpensive to build and repair. Itwas to overcome these' objectionable defects in prior joggers thatthepresent invention was conceived.

The main objects of this invention are to provide a novel, improved,inexpensive and transportable jogging machine; to provide such .a devicewhich is adjustable and adaptable to sub- 'stantially all types ofprinting, binding and trimming machines and machines used in alliedindustries; to provide a device of this character which. may beconstructed of wood or other light inexpensive material; to provide adevice of this character having a pivotally operated tray disposed on ahousing cover and having an oscil1at-.

ing action transmitted to it by means of a motor; to provide a device ofthis character having adjustable means to accommodate different sizesand weights of paper; to provide a device of this character in which themotion of the jogger tray is in a single plane normal to the singlerigidly mounted tray supporting pivot located off geometric centerof thetray; and to provide a device of this character which is simple inconstruction, safe, convenient and simple to operate and readilyadjustable to different sizes and weights of work.

An illustrative embodiment of this invention is shown in theaccompanying drawings in which:

Figure 1 is a top elevational view of my invention.

Fig. '2 is a sectional view taken on the line 22 ofFig. .1.

Fig. '3 is a sectional view taken on the line 3-3 of Fig. l. 1

Fig. 4 is a vertical sectional view of the pivot member taken on theline 4-4 of Fig. 1.

Fig. 5 is a face view of the eccentric member.

Referring in detail to the drawings, the-housing generally indicated bythe numeral l is preferably constructed of wood, or a similar lightweight material and comprises a base 2, a pair of'side frame members 3and 4, the upper edges of which are diagonally disposed, as clearlyshown in Fig. 2, a front frame member 5 and a top or cover plate member6 secured to the upper edges of the side frame members 3-4. It will beapparent from Fig. 2 that the top 6 lies in a diagonal plane.

A jogging tray generally indicated by the numeral 1 comprises a base 8,a side wall 9, a front wall I0, and an adjustable end frame H. The

end frame H comprises a pair of side walls J2 and I3 attached in anysuitable manner .to base I 4. The entire end frame I I is adjustabletoward and away from sidewall 9 and is held in position on base 3 by thebolt 5 and wing nut IS. The bolt I5 is inserted and seats in .any one ofthe spaced apertures lllocated in side. wall 10 in accordance withthesetting desired; v

The tray '1 is positionedin parallel relationship to the top 5 of thehousing I and is spaced away therefrom by means of an anchor pivot, Theanchor pivot is fully illustrated in Fig. 4, and comprises two flangedcollar members I 8 and is having a shaft 28 common to both of'them.Col.- lar I9 is anchored to. shaft 20.by any suitable means, such asbyrivet 2|, so as tomake. the

collar l9 and shaft 20 a single unit. .Collar l9 7 is secured to theunderside of base 8 ofthe .tray 1- by any suitable means, such, as byscrews 22 passing through apertures in the, flange portion ofcollar l9..j

Collar I8 is anchored. to the lower face of top 6 vof the housing Ibybolts 23 ,23 andnuts 24-24 which pass through apertures located in theflange of collar.l8. It thus becomes apparent that the tray 1 ispiovtallyanchored to the housing l and that the collar l8 acts as abearing for the shaft 20. p i 7 To prevent displacement and play in. thecollar-bearing l8, .a retention collar 25 is secured to the shaft 20' byany suitable means, such as by a set screw 2%. It will be noted thatthev pivotal connection is located off dead center, i. e.,v the verticalaxis of both the tray and housing.

The oscillating action of the tray is accomplished by the mechanismlocated within housing I', and comprises a motor 21, connected toan-electrical source in the usual manner and is con.- trolled by switch28. Motor 21 is anchored to base 2 in any suitable manner such asbybolts 29. A pulley wheel is attached to the motor shaft 3| in anysuitable manner, such as by set screw (not shown). A large pulleywheel-32 is securedto one end of thedriven shaft 33 and is connected tothe pulley wheel 30 by belt 34.

Shaft 33 is located forward of the motor and is journaled inbearingblocks 35-35 having oil cups 37-31 located on the upper surfaceof the blocks 35-35 to lubricate the shaft 33. The bearing blocks 35-35are anchored to the support block 38 which is anchored'to the -base 2. Aflange 35 having a collar-36"is'secured-to driven shaft 33 in ansuitable manner at the end opposite pulley wheel 32. A rectangular plate40 is secured to outer face of the flange 33 by screws l |4l andcontains stub shaft 39 mounted on said plate 40 eccentrically of theaxis of the shaft 33.

One end of link arm 42 is provided with an aperture in which saideccentric stub shaft 39 seats and extends therethrough. The distal endof shaft 39 is threaded and provided with a lock washer 44 and nut 45whereby to retain the arm 42 on said shaft 39. The free end Q2 of arm 42is threaded. A second link arm 13 is provided with a threaded bore 43'into which the threaded end 42' is loosely threaded as shown in Fig. 3.

A rod 45 is slidably mounted in spaced bearing blocks 4e se which areanchored to an upright supporting frame 41 in any suitable manner suchas by bolts 48. One end of rod 45 extends beyond the forward bearingblock and is pivotally secured to the free end of arm 43 by a bolt 59and nut 58. It will be apparent from Fig. 3 that arm as and rod 45 areprovided with aligned apertures through which the bolt 59 is looselythreaded. The arm 43 and rod 55 are spaced away from each other by awasher 5!. A pivot collar 52 is anchored to rod is, substantiallymedially oetween bearing blocks AG-45, by means of a bolt 53, whichextends through suitable apertures in rod 45, and nuts 54. Washer 55serves to minimize friction. It will be apparent Fig. 2

that the collar is pivotally mounted to said rod on an axis normal tothe axis of said rod. The lower end of connecting shaft 56 is slidablyheld in collar 52, a set screw 5'5 being provided in the collar forlocking the shaft to the collar during shipment so as to support thecantilevered end of the tray 1. The upper end of shaft 53 is fixed inthe flanged collar 58 in any suitable manner, such as by set screw 53.Collar 58 securely attached to the underside of base 8 of tray 1 andextends downwardly into aperture 6t located in housing cover 6.

Power is transmitted from motor 21 to driven shaft 33 by means of thebelt es. Driven shaft 33 rotates the flange 36 and its eccentricallypositioned stub shaft 39 which in turn transmits motion to link arms 42and 43 and they in turn reciprocate rod 45 which imparts oscillatingmotion to the tray 1 by means of the connecting shaft 56 about pivot 20.

The material to be jogged is fed over and slides across the top edge ofend frame I i, such method of feeding causing the sheets of paper, orother material used, to become separated by retarding and separatingeach sheet and thus allowing an air pocket to come between each sheet.By the action of the machine, the sheets are then jogged into the cornerwhich is formed by the intersection of side walls 9 and It and formedinto a uniform mass. I have found that my invention functions mostefficiently when a motor of A to A; horse-power is geared down tooperate from 400 to 800 R. P. M., depending upon the material to bejogged.

It will be apparent from the foregoing that by using the pivotal collar52 and loose threaded connection between the arms 42 and 43 all wobblemotion usually present in apparatus of this character is eliminated andonly a forwardly and backwardly oscillatory motion is imparted to thetray 1 about the axis of the pivot shaft 2@.

It will be understood that some of the details set forth may be alteredor omitted without de parting from the spirit of the invention asdefined by the following claims.
